Animation: The World’s Largest Megacities by 2100

Throughout the course of human history, the biggest cities have always seemed impossibly large.

For many millennia, it was almost unfathomable for a city to sustain more than 1 million residents. In fact, it wasn’t until the 19th century that the largest cities globally, such as London and Beijing, were able to consistently hold populations beyond that impressive mark.

Despite this, in the modern era, we’ve quickly discovered that a city of 1 million people isn’t remarkable at all. In China alone, there are now over 100 cities with a million people today – and as such, our mental benchmark for what we consider to be a “big city” has changed considerably from past times.

Thinking Big

Just like a city the size of modern Tokyo was hard to imagine for someone living in the 19th century, it can be an extremely difficult thought experiment for us to visualize what future megacities will look like.

Researchers at the Global Cities Institute have crunched the numbers to provide us with one view of the potential megacities of the future, extrapolating a variety of factors to project a list of the 101 largest cities in the years 2010, 2025, 2050, 2075, and 2100.

Today’s video uses this data – it’s also an extension to the previous work we did based on the report here.

The Largest Megacities by 2100

According to the report, human geography will look completely unfamiliar by the turn of the century.

Here is a list of the 20 largest megacities projected for 2100:

RankPopulation (2100)CityCountry

#283.5 millionKinshasaDRC
#373.7 millionDar Es SalaamTanzania
#467.2 millionMumbaiIndia

#1740.0 millionManilaPhilippines
#1837.7 millionLusakaZambia
#1936.4 millionMogadishuSomalia
#2035.8 millionAddis AbabaEthiopia

By the year 2100, it’s estimated that 13 of the world’s largest megacities will be located in Africa. Meanwhile, India will hold three of them – and there will be zero of them found in the Americas, China, or Europe.

Here’s a final look at the top three:

#1: Lagos, Nigeria
Nigeria’s largest city, Lagos, is expected to push the limits of how big a metropolis can get. Already, Lagos has seen explosive growth over the past few decades, and is growing so fast that no one really knows how many people live there. Over 2,000 people emigrate to the city every day, and current population estimates vary widely from 11 to 21 million inhabitants.

Either way, by the turn of the century, Lagos is projected to have a population north of 88 million.

#2: Kinshasa, DRC
Kinshasa, the capital of the Democratic Republic of Congo is projected to be the second largest city in the world with a population of 83 million.

#3: Dar Es Salaam, Tanzania
Dar Es Salaam, a city on the coast of Tanzania, has a population of just 4.4 million today. By 2100, its population is projected to jump by a whopping 1,588%, putting the total at 74 million inhabitants.

10 Travel Destinations for Post-Pandemic Life

Excited to get back to travelling the world? This infographic highlights the 10 most popular tourist destinations.

10 Travel Destinations for Post-Pandemic Life

On March 11, 2020, the World Health Organization formally classified the COVID-19 outbreak as a pandemic. The resulting travel bans decimated the tourism industry, and international air travel initially fell by as much as 98%.

Almost two years later, travel is finally back on the table, though there are many restrictions to consider. Regardless, a survey conducted in September 2021 found that, as things revert to normalcy, 82% of Americans are looking forward to international travel more than anything else.

To give inspiration for your next vacation (whenever that may be), this infographic lists the 10 most visited countries in 2019, as well as three of their top attractions according to Google Maps.

Bon Voyage

Here were the 10 most popular travel destinations in 2019, measured by their number of international arrivals.

CountryNumber of international arrivals in 2019 (millions)
🇫🇷 France*90.0
🇪🇸 Spain83.5
🇺🇸 U.S.79.3
🇨🇳 China65.7
🇮🇹 Italy64.5
🇹🇷 Turkey51.2
🇲🇽 Mexico45.0
🇹🇭 Thailand39.8
🇩🇪 Germany39.6
🇬🇧 United Kingdom39.4

France was the most popular travel destination by a significant margin, and it’s easy to see why. The country is home to many of the world’s most renowned sights, including the Arc de Triomphe and Louvre Museum.

The Arc de Triomphe was built in the early 1800s, and honors those who died in the French Revolutionary and Napoleonic Wars. In 1944, Allied soldiers marched through the monument after Paris was liberated from the Nazis.

The Louvre Museum, on the other hand, is often recognized by its giant glass pyramid. The museum houses over 480,000 works of art, including Leonardo da Vinci’s Mona Lisa.

Art isn’t the only thing that France has to offer. The country has a reputation for culinary excellence, and is home to 632 Michelin-starred restaurants, the most out of any country. Japan comes in at second, with 413.

While You’re There…

After seeing the sights in Paris, you may want to consider a visit to Spain. The country is the southern neighbor of France and is known for its beautiful villages and beaches.

One of its most impressive sights is the Sagrada Familia, a massive 440,000 square feet church which began construction in 1882, and is still being worked on today (139 years in the making). The video below shows the structure’s striking evolution.

At a height of 172 meters, the Sagrada Familia is approximately 52 stories tall.

Another popular spot is Ibiza, an island off the coast of Spain that is famous for its robust nightlife scene. The island is frequently mentioned in pop culture—Netflix released an adventure/romance movie titled Ibiza in 2018, and the remix of Mike Posner’s song I Took a Pill in Ibiza has over 1.4 billion views on YouTube.

Beaches Galore

If you’re looking for something outside of Europe, consider Mexico or Thailand, which are the 7th and 8th most popular travel destinations. Both offer hot weather and an abundance of white sand beaches.

Expect Turbulence

Under normal circumstances, hundreds of billions of dollars are spent each year by international tourists. According to the World Travel & Tourism Council (WTCC), this spending accounted for an impressive 10.4% of global GDP in 2019.

Travel restrictions introduced in 2020 dealt a serious blow to the industry, reducing its share of global GDP to 5.5%, and wiping out an estimated 62 million jobs. While the WTCC believes these jobs could return by 2022, the emerging Omicron variant has already prompted many countries to tighten restrictions once again.

To avoid headaches in the future, make sure you fully understand the rules and restrictions of where you’re heading.

Which Values Children Should Be Encouraged to Learn, By Country

Which qualities do people think are most important for children to learn? The answer differs from country to country.

Published

on

Qualities Children Should Learn

Many of the values we prioritize as adults were instilled in us during our childhood days.

They’re called our formative years for a reason—from when we’re born up until we’re about eight years old, our brains are easily molded and remain highly sensitive to external influences and environments. But depending on where you grew up, you may have been exposed to different values during your childhood compared to someone from another place.

These visualizations by Anders Sundell illustrate the most important values people think children should learn at home, across more than 80 different countries.

Methodology

Sundell used data from the World Values Survey, an international survey that interviews hundreds of thousands of participants from across the globe. Respondents were asked to pick up to five qualities they believe are the most desirable for children to have:

  • Good manners
  • Independence
  • Hard work
  • Feeling of responsibility
  • Imagination
  • Tolerance and respect for other people
  • Thrift, saving money
  • Determination and perseverance
  • Religious faith
  • Unselfishness
  • Obedience

Sundell took the survey data and calculated the proportion of people in each country that selected each quality. From there, he took the top qualities and created three separate plot graphs to show the contrast between them.

Let’s look at the importance that countries placed on different values, including (1) independence and obedience, (2) unselfishness and religious faith, and (3) hard work and imagination.

1. Independence vs Obedience

Nordic countries value independence greatly, and find obedience to be a less important quality to instill in children.

Other available data also supports that adults in Nordic countries value independence. According to Eurostat, the most common age to leave home in Sweden is between 17 and 18—nearly a decade sooner than the average age across the EU (26 years old).

Denmark’s average age to leave home is also below the European average, at 21 years old.

On the other end of the spectrum, countries like Iraq and Egypt believe obedience is much more important for children to learn.

2. Unselfishness vs Religious Faith

Bangladesh, Egypt, and Jordan all place a strong emphasis on faith, and fall on the far right of this graph.

Islam is a strong influence in all three of these countries. In Bangladesh and Jordan, it’s the official state religion. And while Egypt is a secular country, a majority of citizens identify as Muslim—about 90% of the population.

Interestingly, places like the U.S. and Hong Kong fall right in the between, placing relatively equal importance on religion and unselfishness.

3. Hard Work vs Imagination

Left-leaning Nordic countries like Sweden, Norway, Denmark, and Finland think imagination is more important for children to learn than hard work.

Interestingly, Japan also scored high for imagination, seeing it was a more important value to teach children than hard work. This is despite the fact that the country has an international reputation for being a hardworking country, where even taking an extended vacation can be frowned upon. Then again, Japan has a reputation for producing wildly creative works of art that are popular internationally (anime, for instance).

As expected, countries and cultures contain multitudes, and can often seem paradoxical and complex to those who try to codify them.

What qualities do you think are most important, and what countries surprised you with their placements?
